USB BASED LAMP

March 23, 2010

The intention of this USB based lamp is to use the  USB power of the computer to get a light from the LED so that we can save light while working on the computer.The power getting from the USB port of the computer is almost 5v and having a maximum current of 500ma.This power can be used effectively to lit up a 0.2watt led so that we can get a sufficient light from it.

The modifications in this project are we are planning to make a charging circuit which will charge the batteries of 3v so that we can use the lamp when there is no computer power.

Here is picture of the lamp-
